In order to avoid losses in quality and quantity of stock during storing it is necessary to ensure properly prepared warehouses, maintenance of optimal storage conditions and constant control of stored mass. The aim of this study is to analyze the status of stored goods and the presence of harmful entomofaune on wheat and maize samples collected from silo Vupik d.d. Vukovar, in the period from March to June 2017. Sample analysis were performed at the Laboratory for Post-harvest Technology within the Department for Plant Protection at the Agricultural Faculty in Osijek, Sampling was performed in 3 terms, each sample weighed 1 kg and was divided into 4 samples each weighing 250 grams. A total of 24 samples were analyzed. The grain temperature, moisture and the hectolitre weight were measured for each sample. Based on the collected data, the initial period of self-heating of wheat grain is noticeable, while the values of moisture and hectolitre weight were within optimal values. A very strong attack of rice weevil in wheat samples was estimated in June. In maize, the presence of rice weevil was recorded in June, when an average attack was estimated. According to the state of stored goods, it can be concluded that the performed fumigation measure was not properly implemented, while immature stages (eggs, laevae and pupae) of rice weevil were left unsuppressed
